Note : Both Netscape and Internet Explorer support the Elements collection (Netscape call it an array).
The Elements collection is an ordered, indexed array, containing a reference to every element on a
<FORM> object. The collection is ordered by source order i.e. the order that the elements appear in the document. The Elements collection consists of
<TEXTAREA> elements. (See those topics for details of the elements properties, methods and events.
Elements Objects would normally be retrieved by their index in the Elements collection (for example
document.<FORM>reference.elements(3) contains a reference to the 4th element object on the referenced
<FORM>), but a string value can be used, as long as that string is a valid identifier (
ID attribute value) for an element in the referenced
length property returns the number of elements in the collection. Note that the
length count starts at 1, not 0 as the elements collection index does. Therefore, the
length property may return a value of 5, but to access the 3rd element, you'd need to use
item method retrieves single items, or sub-collections from the elements collection. It accepts the following arguments:
index is a number, then the method returns a reference to the element object at that position in the elements collections index. I.e.
strTag be the
tagName property ('INPUT' for
<INPUT>, 'SELECT' for
<SELECT> etc.) for the third element contained on the
<FORM> referenced by
index property is a string value, then the
item method returns a sub-collection, containing a reference to every element in the referenced
<FORM> that has its
NAME attribute set to the string contained in the
index argument. To retrieve certain element objects from this sub-collection, the
sub-index argument must be used.
tags method returns a collection of element objects whose
tagName property is the same as the
tag argument used for the method. This differs from the
item property in that that interrogates
NAME values if necessary.
would return a collection of all the
<INPUT> objects in the referenced
